A new technology is able to use ordinary light to create holographic images, opening to door to 3D displays without the need for special screens or glasses. The new technology will use the diffraction of free electrons on thin metal films. When the electrons are excited by incoming protons, they begin to emit colored light at a specific wavelength. These excited electrons will emit a different color of light depending upon the angle of the incoming proton, and bouncing this light...

I wish there was a new portable technology that could extract hydrogen to produce electricity while also converting non-potable water into drinking water. The technology would utilize a new aluminum alloy that, when immersed in water, would split the water into hydrogen and oxygen molecules. The hydrogen could fuel power cells, and drinking water could be harvested from the steam. The method would be ideal for remote areas, needing only the small reaction vessel and the fuel cell...

Ocean floating solar/wave domes connected by a web-like array could be used to harness both sun and wave power. The concept involves connecting dome shaped solar cells in an orderly network. The photovoltaic covered domes would harness solar power while they also capture wave energy as they bob on the water. Solar energy reflected back to the photovoltaics from the water would increase the solar capture by as much as 20 percent.

In an effort to slow coastal erosion, why not develop concrete cylinders that can cancel out up to 90% of a wave's intensity? The cylinders will be hollow with narrow slits in the sides and will cancel out the wave's energy. The cylinders should even be able to handle tsunami waves, and it will be possible that current wave power generation systems could be adapted to the coastal protector technology.

The idea with that artificial rainbow is fantastic. A rainbow machine has been already created. It uses reclaimed rainwater and sunlight to create rainbow effect. The machine applies jet pumps and custom fountain nozzles to spray water in the air, and then the sunlight shines through to create the rainbow effect.

It was found that transplanting a mother's stem cells into her fetus could be a treatment for genetic blood diseases before birth. Stem cell transplants could prepare the fetus for a bone-marrow transplant from a tissue matched donor after birth. Standard bone-marrow transplants usually require the recipient to take immunosuppressive drugs for the rest of their life, but a dose of maternal tissue matched donor cells could prime the developing fetus's immature immune system for...

I want to create a device to prevent fires? It will be a small canister placed inside a wall and connected to an electrical outlet. This device will monitor the temperature of the outlet: in case it reaches 250 degrees (combustion occurs at 426 degrees), the canister will eject special foam that will cool the wires, displace oxygen and insulate the surrounding combustible materials. The foam spilt out of the outlet indicates that a fire has been prevented and that the outlet should...

I've just found out that there is a material, made out of graphite, as thin as a sheet of paper and 10 times stronger than a sheet of steel. The graphene paper is created by milling and purifying raw graphite in a chemical bath, which changes its structure and allows it to be pressed into sheets. The thermal, electrical, and mechanical properties of the sheets allow them to have a wide range of applications in many industries, such as automotive and aviation, with the added...

The idea is to use a new technology to create plastic from sewage. The process will transform sewage into a biodegradable plastic by first removing the water and certain solids. A group of bacteria that address different parts of the sewage, such as sugars or fats, then will work together to produce a bioplastic polystyrene that will be similar to the top of a disposable coffee cup. The bioplastic resin will biodegrade within 6 to 12 months.

The same chemical used as a pigment in breakfast cereals could lead to the creation of LEDs that are grown or printed on the surface of paper. To create the printable diodes, it is necessary to first grew nanometer-sized zinc oxide crystals by coating paper in a polymer, seeding it with a solution containing zinc, and then coating it again with another polymer. The paper is then dipped in a mixture that encourages the zinc to grow into upright hollow rods, with yet another polymer...
